Abstract

A radio frequency (RF) front end device has a signal traveling from a first antenna to a second antenna in an uplink path and a signal traveling from a third antenna to a fourth antenna in a downlink path. The device is under the control of automatic on/off controller (AOOC) which upon receiving a signal indication from a receive signal detector and amplifier (RSDA) turns on the operations of power amplifier (PA) and simultaneously turns off a low noise amplifier (LNA). This LNA is turned off when the power amplifier is turned on to prevent uplink path and downlink path forming a feedback loop which would result in oscillation, noise and interference.
